I can confirm that various operations are much speedier now, including
booting my Debian. This is quite awesome. What is not as awesome that
distributions etc. never questioned especially the debug features
being enabled :) But that's understandable of course given how much
stuff there is generally that only one person is actively dealing with
etc.
Could someone with access rights disable debug and pre-empt features
in gta02_moredrivers_defconfig in git.openmoko.org? I think wrong
stuff there leads to the information not spreading widely enough.
